Selecting a ControlLogix System

The ControlLogix system architecture provides sequential, process, and

motion control together with communications and state-of-the-art I/O in a

small, cost-competitive package. The system is modular, so you can design,

build, and modify it efficiently - with significant savings in training and engineering.

A ControlLogix system can be anything from a simple chassis to a highly-distributed

system consisting of multiple chassis and networks working together.

A simple ControlLogix system consists of a stand-alone controller and I/O modules in a single chassis.

Or you can use the ControlLogix system as a gateway. Include the

communication modules you need for connectivity to other networks. For

this use, a controller is not required. The ControlLogix Gateway integrates

into existing PLC-based systems so that users with existing networks can

send or receive messages to or from other networks.

For a more robust system, use:

• multiple controllers in a single chassis

• multiple controllers joined across networks

• I/O in multiple platforms that is distributed in many locations and

connected over multiple I/O links

The RSLogix 5000 programming environment and/or NetLinx open network architecture are common to these Logix platforms. 

The RSLogix 5000 environment offers an easy-to-use IEC 1131-3 compliant interface, 

symbolic programming with structures and arrays for increased productivity, 

and an instruction set that serves sequential, motion, process and drives applications.

The NetLinx open network architecture offers common communication tools for use with a variety of networks such as Ethernet, ControlNet and DeviceNet.

The ControlLogix control platform is:

seamless 

enables easy integration with existing PLC-based systems. Users on existing net works can send or receive messages to/from program controllers on other networks transparently.

fast

the ControlLogix platform provides high-speed data-transfers across the backplane

and the ControlLogix5550 controller provides a high-speed control platform.

scalable

provides a modular approach to control. Add as many or as few controllers and

communication modules as you need. You can have multiple controllers in the

same chassis. Select the controller memory size that meets your application.

industrial

offers a hardware platform designed to withstand the vibrations, thermal extremes,

and electrical noise associated with harsh industrial settings.

integrated establishes a platform that integrates multiple technologies, including sequential,motion, drive, and process applications.

compact

meets the needs of many applications where control is highly distributed and panel

Barrel Control

Select barrel control for multiple–zone applications in which there is

thermal conduction between the zones. Injection molding and

extrusion are good example applications because they use multiple

heater bands (zones) mounted on one thermal conductor (the metal

barrel). The barrel conducts heat between different zones. If you

select barrel control, also select between inner and outer zones (word

1, bit 13 for channel 1). A barrel loop is autotuned as the temperature

rises from a cold start to a temperature setpoint during startup.

DH-485 channel offers:

• configurable isolation via the 1747-AIC or 1761-NET-AIC interfaces.

• maximum network length of 1219 m (4000 ft).

• RS-485 electrical specifications.

• Belden 9842 or Belden 3106A cable connection between nodes (daisy-chain connection).

Introducing ControlLogix for High Performance Control

ControlLogix provides a high performance control platform for multiple types of control. 

You can perform sequential, process, drive or motion control - in any combination - with this single plat form. 

Because the platform is modular, you can design, build, and modify it efficiently - with significant training and engineering savings.

Engineering Productivity is increased with advanced configuration tools, 

memory structure and symbolic programming that requires less programming and memory. 

And your investment in ControlLogix is assured through with such features as flash-upgradable firmware. 

The flexible ControlLogix platform permits multiple proces sors, networks, and I/O to be mixed without restrictions. 

As your application grows, you can use the NetLinx architecture for control and configuration of devices and collection of information

across Ethernet, ControlNet, DeviceNet and Foundation Fieldbus networks.
